Movahed MohammadiEnvironmental problems such as air and water pollution, urban garbage and climate changes in urban areas are the results of human behavior. Only change in human behavior can reduce these environmental problems. Thus studying attitude and behavior of people is a precondition to change this situation. So the main objective of this study was to find out individual and social … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval and Recovery of Uranium using Microorganisms Isolated from North American Uranium DepositsTakehiko TsurutaSome attempts were made to remove and recover uranium that may be present in nuclear fuel effluents and mine tailings using microorganisms isolated from North American uranium deposits. To establish which microorganisms accumulate the most uranium, hundreds strains of microorganisms were screened. Of these strains of microorganisms tested, extremely high uranium accumulating ability was found in some bacteria isolated from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Purification of Bacterial Strains from Treatment Plants for Effective and Efficient Bioconversion of Domestic Wastewater SludgeK. C.A. Jalal, Md. Z. Alam, Suleyman A. Muyibi, P. JamalForty six bacterial strains were isolated from nine different sources in four treatment plants namely Indah Water Konsortium (IWK) sewage treatment plant, International Islamic University Malaysia (IIUM) treatment plant-1,-2 and -3 to evaluate the bioconversion process in terms of efficient biodegradation and bioseparation. The bacterial strains isolated were found to be 52.2% (24 isolates) and 47.8% (22 isolates) in the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Analysis of an Absorption/Compression Refrigeration System Using Geothermal EnergyL. Kairouani, E. NehdiThis article presents the potential use and exploration of geothermal energy for cooling applications using a combined absorption/compression system. The considered system uses R134a for the compression part and the cool water-ammonia for the absorption part of the installation. The geothermal temperature source is in the range 343-349K, the condensation temperature is 308 K, and in order to produce ice, … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,554 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordThe Synopsis of Environmental Heavy Metal PollutionAnyiam N. Donald, Pene B. Raphael et al.Heavy metal pollution continues to be a serious problem in the environment due to uncontrolled pesticide use, mining, foundry operations, smelting, fossil fuel burning and sewage sludge dumping. Mercury, lead, chromium, cadmium, copper and other heavy metals are non-biodegradable and remain in the environment in regions where human activity is prevalent. Heavy metal contamination is a serious hazard to all … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 7 Dec 2022 · 8,323 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPHENOTYPING, VIRULENCE CHARACTERISTICS OF AEROMONAS SPECIES AND THE EFFECTS OF ESSENTIAL PLANT OILS AS ANTIMICROBIAL AGENTS AGAINST PATHOGENIC ISOLATES FROM DIFFERENT SOURCESAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Nihad A.M. El-NasharAeromonas species are increasingly recognized as enteric pathogens. Faecal samples from 20 cow, 45 sheep; 60 goat and 60 camels were examined for the presence of Aeromonas species, which was also sought in the available drinking water (55 well water and 52 drinking chlorinated tap water were also examined). Aeromonas species was isolated more frequently from goats (21.7%) than from … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 18 Jan 2014 · 8,020 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDFCite
